OG-13

13. Defense Department analysts worry that the ability of the United States to wage a prolonged war would be seriously endangered if the machine-tool manufacturing base shrinks further. Before the Defense Department publicly connected this security issue with the import quota issue, however, the machine-tool industry raised the national security issue in its petition for import quotas.

Which of the following, if true, contributes most to an explanation of the machine-tool industry’s raising the issue above regarding national security?

A. When the aircraft industries retooled, they provided a large amount of work for too builders.

B. The Defense Department is only marginally concerned with the effects of foreign competition on the machine-tool industry.

C. The machine-tool industry encountered difficulty in obtaining governmental protection against imports on grounds other than defense.

D. A few weapons important for defense consist of parts that do not require extensive machining.

E. Several federal government programs have been designed which will enable domestic machine-tool manufacturing firms to compete successfully with foreign toolmakers. C

谁能帮忙讲一下这道题目的思路？？？

     原文推理：Defense Department害怕machine-tool manufacturing base 下降后导致美国无能力发动长期战争，（因此Defense Department想要保护machine-tool industry），用什么办法保护呢？？Defense Department希望减少进口配额（将生意给本国的machine-tool industry，从而使得企业生命力更强），但是Defense Department发现machine-tool industry已经用国家安全问题为借口寻求进口配额限制了

    问如何解释machine-tool industry已经用国家安全问题为借口寻求进口配额限制？

    C说machine-tool industry除了用国家安全为借口，没有其他很好的理由去要求政府限制进口

不好意思，我没有收到回帖的短消息，所以一直没有看。。首先谢谢kingsoft的解答。

The machine-tool industry encountered difficulty in obtaining governmental protection against imports on grounds other than defense.

看来这句话的翻译还是最关键的，我理解成了machine-tool industry是在寻求国家进口配额保护而不是国家防御上遇到了困难，你说我这样的理解对吗？？我还是有点迷糊

不对！

on the grounds other than defense是除了defencse以外的理由，就是说其他的理由都不行，只有defense这个理由行!
